DUPLEX CHECK VALVE MANUFACTURERS IN INDIA

Speciality Valve is one of the leading Duplex check valve manufacturers in India that supplies corrosion-proof and high-grade check valves for industrial use. The valves are constructed from superior-grade Duplex stainless steel and are designed to stop reverse flow and safeguard equipment and piping systems.

Why Required?

Check valves play a significant role in processes that have backflow protection in order to safeguard the integrity of processes. Check duplex valves are most required where general materials do not survive under corrosive or high-pressure applications, with more longer service life as well as providing improved resilience in adverse conditions.

Key Components of Duplex Check Valve:

1) Valve Body: Structured utilizing Duplex stainless steel to provide extra strength and corrosion resistance
2) Disc or Ball: Freely moves to open or close down flow based on pressure levels
3) Seat Ring: Provides a tight seal when the valve is closed
4) Hinge Pin (for swing type): Attaches the disc to the valve body
5) Cover or Bonnet: Closes and gives access for maintenance

Working of Duplex Check Valve:

Duplex check valves function automatically. Under proper flow direction, pressure opens the disc. On reverse flow, the disc closes against the seat to avoid backflow. No operation or actuation by hand is needed by the valves, therefore simple and efficient to accomplish.

Benefits of Duplex Check Valve:

1) Very good pitting, crevice corrosion, and chloride stress corrosion resistance
2) Durable and long-lasting operation in aggressive conditions
3) High strength and toughness for high pressure and high temperature
4) Low maintenance design
5) Prevents pump and compressor damage from reverse flow

Functions of Duplex Check Valve:

1) Prevent backflow in piping systems
2) Protect valves, compressors, and pumps from pressure surges
3) Preserve pressure and process integrity
